' To a]? whom, "/12? may concern.

Be it known that we. JUIIX C. HAskn'rr and Crriniins A. S'rucns, citizens of the United States, residing at Spiceland, in the county of Henry, State of Indiana, have invented a new and useful lntake-lt lanifold Mixing Device: and we do hereby declare the following to be a full, clear, and exact descrlption of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to intake manifold mixing devices, and has for its object to provide a device of this character comprising substantially a flat member adapted to be disposed between the flanges of the intake manifold and the carbureter, said member being provided with anarched central portion arching the aperture in said flat member which registers with the passage in the intake manifold, said arching portion forming means for preventing displacement of he device when the intakemanifold or car- I bureter is removed, said arching device hav-.

ing pivotally mounted thereon and to rotate in a horizontal plane a mixing wheel, which wheel is rotated on the intake'strokes of the pistons of the engine and forms means whereby the gases will be thoroughly mixed and volatilized.

Y With the above and other objects in view the invention resides in the combination and arrangement of parts as hereinafter set forth, shown in the drawings, described and claimed, it being understood that changes in the precise embodiment of the invention may be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawings Figure 1 is a side elevation of a conventional form of carbureter and a portion of an intake manifold showing the device applied between the flanges thereof.

Figure 2 is a top plan view of the device.

Figure 3 is a vertical sectional View taken on line 3-3 of Figure 2.

Referring to the drawings, the numeral 1 designates a conventional form of carbureter and 2 the flange thereof, which flange is connected to the flange 3 of the intake manifold l by means of bolts 5. It has been found that gases which are sucked through the manifold 4 are not sufliciently volatilized and mixed and to accomplish this result a substantially flat member 6 is disposed beto the intake manifold pass. The member 6 is provided with a struck up portion 9 which arches the opening 8 and is provided with a centrally disposed pin 10 which iscaxially disposed in the opening 8 and on which pin a rotatable bladed member 11 is disposed,

and which bladed member on the impulse or suction strokes of the pistons is rapidly rotated by the gases sucked past the same thereby causing the rapidly rotating blades to break up particles of the gases and thoroughly mix the gases in such a manner that the char e is volatilized and consequently the efficiency of the fuel increases.

From the above it will be seen that a gas mixer for internal combustion engines is provided, which mixer may be easily and quickly disposed between the flanges of the wherein the construction is simple and the parts reduced to a minimum.

The invention having been set forth what is claimed as new and useful is 1. The combination with a carbureter and an intake manifold having flange connections, said flange connections being held to gether by bolts, of a mixing device interposed between said flanges, said device comprising an apertured plate having a centrally disposed opening registering with the opening in the intake manifold, a struck out member arching the centrally disposed opening and a bladed wheel pivotally mounted on the struck out portion and axially disposed in relation to the centrally disposed opening and disposed in the same plane as the apertured plate. i

2. The combination with a carbureter and an intake manifold having flanges connected together by bolts, of a gas mixer for mixing the gases as they pass from the carbureter to the intake manifold, said gas mixer comprising a plate interposed between the flanges carbureter and the intake manifold, and one i of the carbureter and the intake manifold and through which plate the flange securing bolts pass, said plate" being provided with intake mariifold,said Wheel being in the same i V a centrally disposed aperture through which plane as the plate. i

the gases pass, an integral struck out arching In testimony whereof We have signed our member arching the opening in the plate and names to this specification in the presence of 5 provided With a portion parallel with the two subscribing Witnesses plate, an axially disposed Wheel pivotally JOHN C.

means whereby the gases will be thoroughly A. R. MGARTHUR,
